What are you going to do to preserve a tradition that is the peculiar and unique culture that Judaism inculcates? The American Jewish community is not going to survive by lining up against its common enemy.
Judaism is much more communal, and partly as a consequence of my religious switch, I am increasingly more suspicous of my previous view that what people do in the privacy of their own home is their business alone.
It therefore become essential for the future of Judaism itself that its advancement should be correlated with a similar effort to advance the cause of religion generally.
What is supposed to be the very essence of Judaism - which is the notion that it is by study that you make yourself a holy people - is nowhere present in Hebrew tradition before the end of the first or the beginning of the second century of the Common Era.
Our society is the product of several great religious and philosophical traditions. The ideas of the Greeks and Romans, Christianity, Judaism, humanism and the Enlightenment have made us who we are.
Every fundamentalist movement I've studied in Judaism, Christianity and Islam is convinced at some gut, visceral level that secular liberal society wants to wipe out religion.
